Hello, one gallon of jet fuel should weigh 6.7 lbs. at a temperature of 60 degrees F. This varies of course, but it is the standard. In extreme temperatures, it will change up to or around 6.55 or 6.85 lbs, but this is measured at least twice daily and adjusted for. It is also taken for long or international flights.
Hope this helps, Mikeclod.

Gasoline (I.E. AvGas) is measured @ 6 LB/Gal generally

So as you can see its less dense than Kerosene (jet fuel)

mind there are us gallons and imperial gallons,
just to complicate things
1 us gallon = 0.83267 imp gallon
1 us gallon = 3.7853 liter
1 imp gallon = 4.5460 liter
these are volume values
for oil the this gives
1 us gallon = 7.5000 lbs

The volume is going to vary based on the temperture of the fuel.

Anytime the tanks where dipped to determine the height of the fuel the temp was also noted.

It was impressive to see the difference in height if you took a barge shipment during the day, where the fuel was heated up as it passed through the pumps and the pipeline to the pumps. We had to wait a day for the static electriciy generated by the fuel moving through the pipeline to bleed off, that gave it usually and evening to cool down. There was sometimes a difference of a couple of feet in height of the fuel in the tank between those two mesurements.



OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.

LanPeru

Here are the figures from my P&WA handbook. These figures are for a standard day; 59 degrees F (15 degrees C) and 29.96 inches of Mercury barometric pressure. These figures are in pounds per gallon instead of gallons per pound.

JP-4 6.55
JP-5 6.82
Kerosene 6.7
Jet A 6.74
Gasoline 5.87

Actually guys, LanPeru is asking "How Many Gallons In A Pound(lb) Of Fuel?", not the weight of 1 gallon of fuel.

So if we're talking Jet-A and use the following:

1 gallon = 6.7 lbs.

Then that would equate to:

.15 gallons = 1 Pound(lb) of fuel

So, there are .15 gallons in a pound(lb) of fuel.

Tricky question LanPeru!

 Big thumbs up

Here are a few conversions to get LBS of fuel

multipy liters by 1.76 to get Lbs
multiply US Gallons by 6.66 to get Lbs
multiply IMP Gallons by 8 to get Lbs
mulitiply Kgs by 2.2 to get Lbs

I've been using the metric system since I was born....

And I think for the most of Europeans is the same thing.......

Yes, but as an American, I've been using the standard system since I was born...

(Frankly, I don't care what system comes out on top--as long as I don't have to convert!)

Well I was born and lived USA for 50 years... until PanAm bankruptcy force me to work overseas... many airlines use metric system (weights) overseas...
xxx
Atlas Air Cargo (USA) uses metric weights and fuel gages in kilos...
xxx
With metric, sure makes computations EASIER...
If you know the specific density of a liquid, much easier to compute weight (in kilos) of a liter of any liquid...
At 15 degrees Celsius...
Gasoline is .690 density (a liter of gas weighs .690 grams or .69 of a kilo)...
JP-4 is .78 density
Jet A-1 is .812 density (a liter of Jet A-1 weighs .812 grams)
Water ... is 1 (1 liter = 1 kilo), all the metric guys know that...
And a liter of mercury would be something like 13 kilos...
xxx
Now if you hate kilos so much, multiply these by 2.2048 to get lbs...
Not too many people NOT using metric nowadays... except USA...
xxx
A little anecdote here, in the mid 1980s I once landed in Gander, short of fuel and ideas to make it non-stop to Boston... Canada had just gone metric, but we forgot that fact, so we put our fuel order in "Imperial Gallons", but the gentleman said "we use liters now"...
So with a smile, I said "shall we call it "Imperial" Liters?..."
I dont think he enjoyed my joke that much... oh well...

If the metric system is officially the Standard International Measure System, it should be the standard system everywhere.

That's why I don't feel confortable when I read 40000 feet.

What does it mean?!?!?!

ANd then the miles aren't miles everywhere, a mile for the ground, a mile for the sea....

But airplanes miles (indicated as possible range) are nautical or terrestrial miles?

Or nautical above seas and terrestrial above the ground.

Kms are much more easy and I think they should be the only measure system.
